7 This invention relates to a device for moistening display postermaterial. V i

The chief object of the invention is to moisten display poster materialand remove from the same the creases and unevenness and substantiallyall stretch.

The chief feature of the invention consists in the provision of meansfor supplying a substantially uniform amountof water to a rela- 39tively absorbent poster medium, whereby the same will be moistened ortempered and remain so for a relatively long period of time withoutdisintegration and will be so arranged that substantially all thestretch and creases will be removed therefrom.

The full nature of the invention'will be understood from theaccompanying drawings and the following description and claim:

In the drawings Fig. 1 is a top plan view 5:9 of a moistening deviceembodying the invention. Fig. 2 is a side elevation thereof, Fig. 3 is atransverse sectional view taken on line 3-3 of Fig. 2, and Fig. 4 is anenlarged transverse sectional view of the poster roll mounting.

In the drawings indicates a framework having suitable compartments 11for reception of rolls of moistened paper posting copy, the same beingwrapped in oil cloth or simi- 39 lar material so as to retain themoisture. A perforated support in the form of a screen or table top 12is supported by the frame 10 and adjacent thereto is a U-shaped trough M13 in which is mounted an open bearing member 14 having the inclinedslot15 therein for receiving the end of the shaft 16. The other end ofthe shaft includes a universal joint 17 connected to a stub shaft 18mounted in a bearing 19 supported by the frame 10. Shaft 18 is driven bya pulley 2O driven by a belt 21 connected to a driving pulley 22 drivenby an electric motor 23 controlled by foot pedal 24 connected by link 25to a control mechanism 26. The trough 13 is adapted to contain water orother moistening liquid and the material to be moistened is rolled underwater and it has been determined that the tension in the roll obtainedin rolling is suificient to permit just sufficient 1927.

moisture to be retained by the material to be moistened. v

. In pasting posters the copy is usually supplied in standard dimensionsheets or certain sizes and multiples thereof. These sheets are suppliedfolded and heretofore it has been the practice to unfold these sheets inthe field adjacent the posting board and moisten them with paste aftermoistening the board with paste, and then mounting the several sheets onthe board, in proper relation to form the entire sign. The presentinvention contemplates unfolding of each sheet at the moistening plantso that all the Wrinkles and creasesand folds, as well as unevenstretching will be removed therefrom. After unfolding upon .theperforated table or top 12, the bottom end of the sheet is passed intothe trough and thence is wrapped 7 around the shaft 16and retainedthereon by an elongated spring clip in 'the form of a partial cylinder27 the copy sheet being represented by the numeral 28. As, the shaft 16is rotated, the copy is passed thru the tank, subjected ,tow'ater andmoistened to the desired degreewhen rolled uponthe shaft. After'thesheet has been entirely moistened and rolled the shaft 16 isremovedthru. the slot 15 from the bearing 14; andelevates sufiicient topermit pulling of the copyfrom the shaft. The rolled copy is thenenclosed in an oil cloth or similar wrapper or containerl and then'takento thefield for posting, The paper so moistened hasuniform stretch. Allthe wrinkles and creases are removed from it and the material remainsina moistened or tempered condition suitablefor [easy handling and willremain in said condition for at .least'a day and it has re mained forseveral days. The resultant roll,

therefore, is such thatthe outer end of the roll is positioned at thetop of the sign board and: the vcopy is paid out therefrom, the rolldropping by gravity and being pasted thereto without further,manipulation other than the previous application of the-adhesive to theboard and-brush pressure.

30 also indicates a similar framework supporting the'motor 2 3 andincluding drawer receiving "compartments 31, each being 1 1' adapted toreceive the full copy for one or more signs. Supported by the frame isthe trough 32 within which is mounted a shaft 33 in a pair of openbearings 34. Mounted on the shaft 33 are the adjustable end plates 35guiding a roll 36 of blanking paper. The roll revolves in the tank andthe paper 37 passes upwardly over a friction and severing strip 38 whichis relatively smooth and serves to scrape the surplus moisture from thepaper 37 and such excess drips on to the drip plate 39 and is returnedto the tank. The sheet 37 is rolled up upon shaft 40 mounted in an openbearing 41 at one end and having a universal connection 42 at theopposite end and the sheet is anchored to the joint in the same manneras shown in Fig. 3 and previously described. The shaft 40 is rotated bythe stub shaft 43 to which it is connected by said universal shaft 42and said stub shaft is rotated by the pulley 44 driven by belt i5 whichis the same as belt 21., said belt passing once around the pulley 22.

A recording device having an indicating arm 51 movable adjacent a scale52 is associated with the shaft 40 so that the amount of blanking papercan be accurately determined in aroll and thus only suflicient papernecessary for the board of work of each Sign or display will be mountedin any one r0 1.

The foregoing device is of such a nature that the employment of theperforated top permits the paper to be sprinkled when clesired, thesurplus dripping thru, and when the paper is passed thru or into thetank the surplus does not creep back along the table supporting theposting material and thus unevenly moisten the unmoistened part of theposter. If the poster were unevenly moistened, uneven stretching orcreasing would subsequently form by reason of uneven stretch in it.

Another advantage that the foregoing arrangement secures is that inrolling the material to be posted under water the tension in the roll issuch that the surplus. water is crowded from the roll and onlysufficient water is retained therein to completely moisten the roll butnot toover-moisten the same. Thus, the following resultant conditions donot obtain with the present device, towit, a roll having an exteriorportion sufliciently moist with an interior insufficiently 'moist, or ininterior sufficiently moist with an exterior excessively moistened so asto disintegrate thematerial when it is handled.

The present device secures the tempering of poster material with justsufficient amount of moisture requisite therefor, evenly distributed andat relatively great speed and with a low laborcost The moistened postermaterial then is in such shape that it can be mounted on the postingpanels or boards without creasing or wrinkling and without applying glueor paste to the printed face of the posting material such as heretoforehas been required.

After the roll has been formed of moistened or tempered paper, the sameis stripped from the shaft and even tho the paper be in a moistenedcondition the same when in rolled formation, has sufficient stability orrigidity so that it will not buckle in the roll and can be handled as ifthe interior were reinforced by the shaft or a supporting rod.

The invention claimed is:

In a poster copy conditioning machine the combination of a frame, areticulated surface for sheet support, a tank, roll driving andsupporting means therein, a roll support detachabiy associated with thedrivingand supporting means, a power means for rotating the driving andsupporting means to roll the sheet while immersed in the tank.

In witness whereof, I have hereunto afl'ixed my signature.
